scala combinations permutations

I have since generalized it for combinations of variables with only 2 values, and added a dash of general Scala-isms. Here's another implementation in Scala that generates permutations in a different way: def permutationsTwo[A](input: Set[A]): Set[List[A]] = { // we use an inner function called "loop" so that we can hide the fact that // we're converting the input set into a list. */ val xsize = l.size /** * Generates the combinations of this list with given length 'n'. An example of a combination is in the cards you are dealt in a poker-hand, out of the possible 52 cards you are drawn 5 (52 choose 5). The order * doesn't matter. In how many ways can a committee of 3 be chosen from a group of 12 people? It's Scala permuted! I () have altered them to be more amenable to programming in Scala.Feedback is appreciated, particularly on anything marked TODO.. The difference between combinations and permutations is ordering. We all know that there are C(12,3) = 220 possibilities (C(N,K) denotes the well-known binomial coefficient). These are an adaptation of the Ninety-Nine Prolog Problems written by Werner Hett at the Berne University of Applied Sciences in Berne, Switzerland. ... and pass the intermediate result to a deciding routine for combinations selection and/or early generator termination.
